and paler preterminal spots ; all these essentially as in luci- 
lius, except as noted in color. Hind wing and under side 
like lucilius. Dark males show a blurring and lack of con- 
trast of the paler and darker areas, both of which are umber 
brown. Rubbed specimens tend to develop an iridescence 
like that of lucilius , but lose the white scaling more com- 
pletely. Female essentially like male (except lack of costal 
fold) but as usual 1 paler, more mottled looking, and with a 
tendency for the paler areas to increase on the outer half of 
the wing. 
Male genitalia (fig. 2) substantially identical with T. 
lucilius . Left valve with upper lobe widely divergent from 
middle lobe, the spinulation on inner surface forming a band 
extending about to base of lobe ; middle lobe of even width, 
sharply curved ventrad, with a rudimentary keel on inner 
face running into its base. Lower lobe slender and some- 
what tapering, separated by its width from middle lobe 
Tubercle at middle of costa with 6 or 8 hairs. Right valve 
with upper lobe tapering toward tip, not densely spined, the 
tip not recurved, but bearing on its inner face a sharp 
raised ridge which is clothed with very tine spinules and 
granules. A similar ridge along or very close to its outer 
edge, more granulose than spinulose, and connected with the 
first by a few granules on the face of the lobe. Middle lobe 
represented by a small sharp tooth overlying face of upper 
lobe ; lower lobe slender, twice as long as upper lobe, widely 
divergent and tapering, with distinct terminal teeth. Un- 
cus as usual ; the left spine nearly straight and right spine 
sharply curved, more pointed than in persius, but sub- 
stantially as in lucilius. 
Type and paratypes from Woods Hole, Mass., July, Cor- 
nell Univ. type no. 1391. Allotype from Decatur, 111., July, 
reared from Baptisia (in U. S. National Museum from 
Barnes coll.). The types were taken in close association 
with Baptisia tinctoria, though the females were not seen 
actually ovipositing. They hovered most persistently over 
tiny dwarf plants in the paths. I have also seen specimens 
that seem to be this from other points in New England, N. 
Car., Pa., Nebr. and Fla., but prefer not to make them types 
as none were associated with food plants. A single speci-
